HENRY J. VAN THIEL, OF STAPLETON, NEW YORK.

IIVPROVED SUSPENDED BUNKER-LAIVYIYP.

Specification forming part of Letters Patent No. 4l, |08, dated January5,1-'G4.

To all whoml it may concern.:

Be it known that I, HENRY J. VAN THIEL, of Stapleton, in the county ofRichmond and State of New York, have invented a new and Improved Lampand I do hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, making a part of this speoication, in which Figure l is afront view of my invention; Fig. 2, a vertical central section of thesame, taken 'in the line x sv, Fig. l.

Similar letters of reference indicate corresponding parts in the twoAfigures.

This invention relates to a new and improved lamp of that class'whichare suspended in the holds of vessels, and are designed for the useof'stokers, engineers, 35e., and conirnonly termed bunker-lamps.77

The object of the invention is to obtain a lamp of the class specified,which will admit of a uniform supply of oil to the flame so long as anyofthe former remains in the fountain of thelamp,and at t-he sameti meprevent all leakage or overflow of oil hitherto occasioned by theswinging of the lamp under the motion of the vessel.

To enable those skilled in the art to fully understand and construct myinvention,l will proceed to describe it.

A represents the fountain of thelanip,whioh may be constructed of sheetmetal, and has a handle, B, attached to its upper end of bail shape,`and in such a manner as to admit of the fountain Aswinging freely whensuspended on a hook or nail.

The top of the fountain A is made perfectly tight, no opening of anykind being made in it; but there is an opening in the bottom in which ascrew-plug, C, is fitted, and through which the fountain is filled, thefountain being inverted for that purpose.

D is a horizontal tube which projects laterally from the lower part ofthe fountain A, as shown clearly in Fig. 2. This tube contains the wick,and its outer end is curved slightly upward and is expanded in funnelferm.

By this arrangement or mode of construction it will be seen that the oilin the fountain A is prevented from overflowing at the end of thewick-tube D by the pressure of the atmosphere while the flame will besupplied with oil so long as any remains in the fountain.

The ordinary bunker-lamp is supplied with oil at the top,and it has aWick inserted in its upper end. As the oil is consumed and graduallylowers in the fountain the supply of oil to the iame graduallydiminishes and the flame decreases in brilliancy. The lamp, therefore,requires to be replenished at short intervals, causing considerabletrouble,which is avoided by my invention. The ordinary lamps are alsoliable to overflow around the wick-tube and the oil run down the sidesot' the lamp, a difficulty which is also obviated by my invention.

I do not claim, broadly, a fountain-lamp or one with a wick-tube at itslower partand the oil retained in the fountain by atmospheric'lpressure; but,

Having thus described my invention, Iclaim as new, and desire to secureby Letters Patent, as an improved article of manufacture- A suspended orbunker lamp having its fountain A, provided with a screW-plug,0, in itsbottom, and a horizontal Wick-tube, D,at tached to its lower end, asherein set forth.
